JOHN F. BULLARD, OF SXVANTON, VERMONT.

RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 339,969, dated April13, 1886.

Application filed January 30, 1886.

T 0 all whom, it may concern.-

Be it known that I, JOHN F. BULLARD, a citizen of the United States,residing at Swanton, in the county of Franklin and State of Vermont,have invented certain new and useful Improvements in Railway-Switches;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a plan view of my improved railroad-switch.Fig. 2 is a view of the switch-stand. Fig. 3 is a perspective view ofthe lock.

This invention has relation to railroadswitches; and it consists in theconstruction and novel arrangement of parts, as hereinafter set forth,and pointed out in the claims.

Referring by letter to the accompanying drawings, A B and C D designatethe stationary rails of the main track and side track.

E and F designate the connected switchrails, said switch-rails beingconnected, in the usual manner, by tie-bars T, having clamps U. Theordinary railroad-ties are employed in this construction, and theshifting mechanism is connected with the ties and rails in the mannerhereinafter set forth.

The switch-rails E and F are connected by any suitable number of tierodsT, to insure the proper shifting of the switch-rails when the shiftingmechanism is operated for the purpose. The tie H nearest the tie H, uponwhich the swinging ends of the shifting-rails play, is provided with thehinged flanged look I. This flanged lock I comprises the base-plate I,which is let into the upper face of the tie H, so as to bring the upperfaces of the tie H and the base plate I in the same horizontal plane, inorder to permit the shifting rails to be properly operated. The hingedlock I is provided wit-h vertical side flanges, 1 near its wider end,and its arm J is journaled between the lugs K K, rising from thebase-plate 1, near its outer end. \Vhen the lock I is closed, theflanges 1 close down upon and embrace the base-plate I, and the end 1 ofthe lock I abuts against the outer edge Serial No. 190,313. (No model.)

of the base flange of the switch-rail F. The hinged flanged lock I isprovided with a short rib, M, on its back face, and this rib M isprovided with a longitudinally-disposed guard or slot, N, into which alaterally-extending arm or rod, N, connected to the upper end of a shortlever, 0, projects. This lever O is fulcrumed to one edge of the tie orto the baseplate of the lock, and is connected at its lower end by ashort bar or arm, P, with one end of the shifting or operating rod P.The other end of the operating-rod P is connected with one end of ahorizontal lever, Q, which is fulcrumed on a bearing, Q, at one side ofthe track and between the track and switchstand Q". Near its other endthe lever Q is connected, by a pivoted arm, R, to the doublecrank rod S,which latter is disposed vertically in bearings S S secured to theswitch -stand- Q The crank -rod S is connected by a horizontal rod, T,to the switchrail E by a clamp, U, said rod 'I being pivoted to saidclamp or chair U, so that the ends of the switch-rails may describe thenecessary are while being shifted. By using this coir strnction I canunlock and shift the switchrails without having to cross the track, bysimply operating the crank-rod S.

Having described this invention, what I claim, and desire to secure byLetters Patent, 4

1. The combination, with the main and side tracks and the switch-railsconnected by the tie-rod, and the hinged flanged lock with back rib andguard thereon, of the lever 0, bar P, connected thereto and to theshifting-rod P, the lever Q, the crank-rod, and the arms connecting theswitch-rails to the lever Q, and the crank-rod, substantially asspecified.

2. The combination, with the base-plate I, having lugs K K, of thehinged flanged lock I, provided with the slot N, the lever O, with armN, the bar P, operating-rod P, the lever Q, and rods connecting the lockI with the lever of the switch stand, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. BULLARD.
